T0 aZZ whom it may concern: 7 g

Be it known that I, CLARK FISHER, a Gilli. zen of the United States,residing in the city of Trenton, county of Mercer, and State of. haveinvented certain new and. useful Improvements in Combined Anvils:

New Jersey,

and Vises, of which the following is aspecification.

My'invention relates to such anvils as are,

1n various modes of application, provided with a movable vise jawadapted by suitable connections, to be moved into and out of contactwith the body of the anvil, which forms the permanent jaw.

The object of my invention is the construction of a device of theforegoing character which shall be both simple in construction anddirect in action, and the parts of which shall possess the advantagethat they may be easily put together and taken apart.

In the accompanying drawings I illustrate and herein I describe a goodform of a convenient embodiment of my invention, the particular subjectmatter claimed as novel being hereinafter definitely specified.

In the drawings, Figure 1 is a side elevation, and Fig.2 a top plan viewof an anvil embodying my invention. Fig. 3 is a transverse sectionalelevation on the line to w of Fig. 1. Fig. 4 is a perspective View ofthe upper portion of the treadle lever.

Similar letters of reference indicate corresponding parts.

In the drawings, A is an anvil of any usual type. At one side of theanvil, and preferably, but not necessarily, at a point within the usualrecess in the side of its base, is located a boss B, embodying a socketO, which is preferably integral with the base. The socketis preferablycylindrical and opens only through the top of the boss. In the side ofthe body of the anvil opposite the boss, are

two notches or indentations a, for a purpose explained hereinafter.

D is a movable vise jaw formed as a separate member but adapted to haveits lower end entered within the socket O, and of such length that whenso entered its upper end will be flush with the upper surface of theanvil. The lower end of said jaw which is entered within the socket, ispreferably formed with a cylindric knob or enlargement d con= formed tosaid socket. The upper end of the movable jaw forms a vise face adaptedto make contact with the anvil, the opposing side face of which iscorrespondingly flat. A draw bar E is adapted to be attached to saidmovable jaw and to pass through'an aperture extending, conveniently, inthe disposition .of

parts shown, through the body of the anvil,

.and, vby-means of this bar, the movable jaw is operated. By carryingthe bar through the anvil it is brought out on the side of the same onwhich the workman usually stands, and also allows of the lever by whichsaid rod 6 5 is moved being fulcrumed upon the body of the anvil itself.The attachment of the bar to the movable jaw is conveniently effected byentering said bar through an aperture d in the jaw, and equipping itsscrew threaded 7o protruding end with a nut e. The aperture in the anvilthrough which the draw bar, as stated, passes, is designated a", and thebar is preferably provided at its extremity beyond the anvil with a heador stop E which limits its inward movement.

F is a lever, cast or forged preferably in substantially the form shown,and designed to operate the draw bar. Intermediately of its length, andat a proper distance below its upper end, the lever convenientlyembodies or is provided with a projection or bend f, and to the crest ofsaid bend is applied what I term a fulcrum bearing f'. The upper end ofthe lever is connected to the outer end of the draw bar in such manneras to be free for the slight play necessary in the change of positionswhich said parts undergo. I find it convenient to effect the connectionby forming in the head F. of said bar E, a vertical 0 slot, e", in whichthe upper end of the lever F is entered and loosely fits.

A spring, G, is preferably interposed between the movable jaw and thebody of the anvil which constitute the two jaws of the 5 vise, so as tomaintain said jaws normally open. In the drawings I show this spring asbeing of the spiral variety, encircling the draw bar, and bearing eitherdirectly or through the medium of washers against the jaw and anvilrespectively. It will now be understood that power or weight applied tothe lever F below its fulcrum, will draw the movable jaw against the jawface of the anvi], and that, upon the release of said lever, the springwill force it away therefrom. The lower end of the lever F may be shapedto conveniently receive whatever kind of 5 power or weight iscontemplated to be applied to it, but I prefer to extend it outward anddownward and to provide its lower end with a treadle t, so that theworkman may close the vise by bearing upon the treadle with his foot. :0As a result of the foregoing construction of the lever, it is, withoutadditional supporting contrivance, maintained in place by the weight ofits lower portion, it bearingthrough the feet f against the notches.

Having thus, described my-invention, I

claim and desire to secure by Letters Patent: i l

1. In combination, an anvil embodying an aperture and provided with asocket, a removable vise jaw separate from said anvil and likewiseembodying an ,aperture and hinged at its lower end in said socket, adraw bar passed through both apertures and at its ends detachablyconnected respectively with the movable jaw and with the lever,a springouter end, retaining devices at each end of said draw bar, a spiralspring encircling said bar between the anvil and the jaw, and a leverentered withinthe slot of the barand embodying fulcrum projections,substantially as setforth. I l

i In testiinony that I claim the foregoing as my invention Ihereuntosign my name this 25th day of October, A. D. 1889.
